Detailed explanation-1: -This spread of particles through random motion from an area of high concentration to an area of lower concentration is known as diffusion.

Detailed explanation-2: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

Detailed explanation-3: -Diffusion, osmosis and active transport are three main ways that molecules and ions can move into and out of cells through the membrane.

Detailed explanation-4: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.

Detailed explanation-5: -In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.
